This question already has an answer here:
I am far from an experienced linux user. I uninstalled the latest catalyst center and installed the new AMD beta driver. The installation seemed to go fine then it said I should restart to avoid instability. I restarted and then the purple screen comes up for a second, some message flashes too quickly for me to read. Then it goes into a black screen with the blinking cursor. Nothing I type on the keyboard registers. I've looked up and down for solutions but everything I've found about boot problems says I need to get into the terminal and type commands.... I can't even get there. I tried holding shift while computer was booting as I saw that in a thread saying it will help load some sort of safe mode. What do I do?
